OpenEmu is an open source project whose purpose is to bring macOS game emulation into the realm of first class citizenship. The project leverages modern macOS technologies, such as Cocoa, Core Animation with Quartz Composer, and other third-party libraries. One third-party library example is Sparkle, which is used for auto-updating. OpenEmu uses a modular architecture, allowing for game-engine plugins, allowing OpenEmu to support a host of different emulation engines and back ends while retaining the familiar macOS native front end.

Take Control

Up, Up, Down, Down, Left, Right, Left, Right, B, A, Start

Why restrict yourself to just the keyboard? Although it is not a requirement, OpenEmu is best used with a peripheral gamepad or controller to interact with your games.

Via the Controller Preferences, simply auto- magically assign buttons with any generic HID compliant USB or Bluetooth game controller.

Plug in your gamepad, select it from the list… and press start to begin your adventures.

Time To Get Organized

Everything in its place. Automatically

We combine some of the best emulation projects together into one beautiful unified application that simply organizes your personal games library. Watch as you drop in backups of your games (ROMs) & they are gracefully added to their appropriate library along with original box art.

Library

One of the standout features of OpenEmu is how it organizes all your games into one unique, unified games library. Watch as backups of the games (ROMs) you already own are gracefully added to their appropriate library and box art is magically added. You can even create your own ‘collections’ mix and matched from different consoles.
